Calories Equation for Women:
| From: | To: |
The daily calories calculation estimates the number of calories a woman needs to maintain her current weight based on her age, height, weight, and activity level. This is based on the Mifflin-St Jeor Equation, which is considered one of the most accurate formulas for calculating calorie needs.
The calculator uses the following equation:
Where:
Explanation: The equation calculates basal metabolic rate (BMR) and then adjusts it based on physical activity level to estimate total daily energy expenditure (TDEE).
Details: Knowing your daily calorie needs is essential for weight management, whether your goal is to lose, maintain, or gain weight. It provides a scientific basis for planning your diet.
Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. For accurate results, measure your weight and height rather than estimating.
Q1: Is this calculator only for women?
A: Yes, this specific equation is designed for adult women. Men should use a different equation that doesn't include the -161 adjustment.
Q2: How accurate is this calculation?
A: It's one of the most accurate formulas for estimating calorie needs, but individual variations in metabolism can affect actual needs.
Q3: Should I eat fewer calories to lose weight?
A: For weight loss, a moderate reduction (typically 300-500 kcal/day less than maintenance) is recommended for sustainable results.
Q4: How often should I recalculate my calorie needs?
A: Recalculate whenever your weight changes significantly (5+ kg) or your activity level changes substantially.
Q5: What if I'm pregnant or breastfeeding?
A: This calculator isn't designed for pregnancy or lactation - consult a healthcare provider for nutritional guidance during these periods.
